Solution :

Look at the equations to substitute the symbols with appropriate operator. In this case following will balance the equations.
@ = Addition (+)
* = Multiply (x)
# = Addition (+)

10 @ 70 * 60 # 90 =
=> 10 + (70 x 60) + 90 = 10 + 4200 +90 = 4300

105 @ 70 * 30 # 85 =
=> 105+(70X30)+85 = 105+2100+85 =2290

80 @ 40 * 50 # 60 =
80+(40×50) +60 = 80 + 2000 + 60 = 2140

Correct Answer is 2140
